Please note, this OEL/ADE monograph also applies to Nafamostat hydrochloride (CAS RN 80251-32-7) and nafamostat mesylate (CAS RN 82956-11-4). Nafamostat mesylate, also known as nafamostat mesilate, (6-amidino-2-naphthyl-pguanidinobenzoate dimethanesulfonate) is the mesylate salt form of nafamostat, a broadspectrum, synthetic serine protease inhibitor, with anticoagulant, anti-inflammatory, mucus clearing, potential antitumor, and potential antiviral activities (2, 3, 4). Nafamostat is used in Asian countries to improve acute symptoms of pancreatitis (acute pancreatitis, acute exacerbation phase of chronic pancreatitis, postoperative acute pancreatitis, acute pancreatitis after pancreatography, traumatic pancreatitis), treat disseminated intravascular coagulation (DIC), and prevent clotting of perfusing blood in extracorporeal blood circuit. Recently, in vitro studies revealed that nafamostat mesylate has antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and an antiinflammatory and anticoagulation effect. Clinical studies are currently ongoing to evaluate the clinical efficacy of nafamostat mesylate in adult patients hospitalized with COVID-19 pneumonia.

Affygility Solutions has an occupational exposure limit (OEL) and control band assignment for this active pharmaceutical ingredient (API). This monograph also contains the acceptable daily exposure (ADE) value.
